If you're hanging out with a new crowd or not in tight with everyone, add intrigue with smoky eyes. "The deep shadow cloaks your eyes, veiling your feelings," explains Kate Lee, a makeup artist for Chanel.

To do: Line your upper lids with jet-black liner, smudged out with a cotton swab. Sweep on a navy shadow, and brush on dark, sexy mascara. Keep the rest of your look subdued-a soft shimmer powder, nude blush, and rose lipstick. Then go for an amber perfume with floral notes (try BCBGMaxAzria Bon Chic Fragrance, $75). "It has an exotic air," says Lapsansky.
